For utilizing any RGB signal throughout a video system, Foxing Hour presents Luma, an RGB to Y greyscale converter module that compactly fits stellar utility into 4HP. Starting at the top, Luma accepts any mix of R, G, and B signals and sums them down to an equally distributed grayscale “Y” output, representing the luminance intensities visualized and perceived by the human eye. Luma also features an inverted Y signal for opposite effects as well as a buffered RGB pass-through output to utilize elsewhere. Luma allows you to utilize RGB signals as luma signals for further processing, layering, and controlling elsewhere throughout your rack, making it a highly versatile tool for any video-synthesist’s rack.
